Life-cycle Assessment of Carbon Dioxide Capture for Enhanced Oil Recovery

Abstract

The development and deployment of Carbon dioxide Capture and Storage (CCS) technology is a cornerstone of the Norwegian government's climate strategy. A number of projects are currently evaluated/planned along the Norwegian West Coast, one at Tjeldbergodden. CO 2 from this project will be utilized in part for enhanced oil recovery in the Halten oil field, in the Norwegian Sea.We study a potential design of such a system. A combined cycle power plant with a gross power output of 832 MW is combined with CO 2 capture plant based on a post-combustion capture using amines as a solvent. The captured CO 2 is used for enhanced oil recovery (EOR). We employ a hybrid LCA method to assess the environmental impacts of the system. The study focuses on the modifications and operations of the platform during EOR. We allocate the impacts connected to the capture of the CO 2 to electricity production, and the impacts connected to the transport and storage of

Current State of Development of Electricity-Generating Technologies: A Literature Review

“…Capture, transport and storage of CO 2 contribute less than 10% to overall life-cycle CO 2 emissions. This is confirmed in a detailed LCA study of a post-combustion system in Norway by Hertwich et al [40], however Pehnt and Henkel [72] arrive at values of less than 1% for this stage. Hertwich et al [40] studied a combined-cycle power plant equipped with post-combustion carbon capture and storage used for enhanced oil recovery.…”

Hertwich et al [40] studied a combined-cycle power plant equipped with post-combustion carbon capture and storage used for enhanced oil recovery. Allocating the energy and emissions overheads of CO 2 transport and injection to the oil recovery, they arrive at greenhouse gas emissions for the power plant of only 75 g/kWh.…”

Life cycle assessment of hydrogen production from underground coal gasification

“…An iterative methodology is adopted to match an assumed diameter value with the calculated value obtained from the model [44]. CO 2 pipeline is manufactured from carbon steel, with a wall thickness of 15 mm [45][46][47]. Pipeline construction is also associated with use of a trencher.…”

The role of CO 2 purification and transport networks in carbon capture and storage cost reduction

“…As EOR can provide important stimulation for CCS deployment by reducing the overall costs of CO 2 capture and transport, thereby reducing the investment risk [41], it is critical to attract this EOR market with a low CO 2 price [29]. Although CO 2 -EOR oshore has yet to be done in the North Sea, studies have shown the feasibility and benets that could be brought on by its deployment [42,43,44,45].…”
